PPPoE session not automatically reconnecting every 24h – Netduma R3 (firmware 4.0.540)

[JOSHR3ll]

I am experiencing a reproducible issue with my Netduma R3 running firmware version 4.0.540.

Network setup:

• Fiber connection

• ONT: Nokia G-240G-E

• Connection type: PPPoE

• VLAN ID: 2 configured on the WAN interface

• Router: Netduma R3 connected directly to the ONT

Problem description:

Every time I reboot the router, the internet connection works normally. However, exactly 24 hours later the internet connection stops working.

The WAN link remains physically up, but there is no internet connectivity until the router is rebooted.

Observation:

If I reboot the R3 at 14:00, the connection stops working the next day at 14:00 almost exactly. This strongly suggests the PPPoE session expires after 24 hours and the router does not automatically reconnect.

Diagnostic test performed:

When the problem occurs, instead of rebooting the router I performed the following test:

1. I disconnected the Ethernet cable between the Nokia G-240G-E ONT and the Netduma R3.

2. I waited approximately 10–15 seconds.

3. I reconnected the Ethernet cable.

Result:

The internet connection immediately comes back without rebooting the router.

This indicates that forcing the WAN link down/up triggers a new PPPoE session and restores connectivity.

Conclusion:

It appears that when the ISP terminates the PPPoE session (likely due to a 24-hour session timeout), the Netduma R3 does not automatically renegotiate the PPPoE connection unless the WAN link state changes or the router is rebooted.

Request:

Could you please investigate whether this is a PPPoE reconnection issue in firmware 4.0.540?

If possible I would appreciate:

• confirmation whether this behavior is a known issue

• guidance on any configuration change that could resolve it

• or a firmware fix that restores automatic PPPoE reconnection after session expiration.

Please let me know if you need additional information such as logs, screenshots, or further diagnostic tests.
